Racing catalytic converter

When tuning the 1.8T, many car owners focus on a better, more robust sound and a clearly noticeable increase in power under the hood—but especially in this era of environmental stickers and the like, emissions levels are playing an increasingly important role. As part of the exhaust system, the catalytic converter is a vital and even mandatory component used to convert harmful emissions into harmless ones.

• Carbon monoxide is converted to carbon dioxide
  
  Especially in gasoline engines, carbon monoxide CO is produced when fuel combustion is incomplete – a gas that is hazardous to humans. It is converted into the less hazardous CO2 (carbon dioxide).

• Nitrogen oxides are converted to nitrogen
  
  In most cases, nitrogen oxides are emitted into the atmosphere in the form of nitric oxide (NO). Often produced at high combustion temperatures, this toxic gas can be converted into nitrogen by the catalytic converter.

• Hydrocarbons (HC) are converted into water vapor
  
  These gases are produced by incomplete combustion and, in certain quantities, are even carcinogenic. For this reason, a catalytic converter is extremely important here as well to convert the harmful HC into water vapor.

Why is a racing catalytic converter beneficial?

To answer that, it helps to take a closer look at the catalytic converter. The design of a racing or sport catalytic converter is always very similar in appearance. For example, the 1.8T racing catalytic converter consists of a honeycomb structure—a feature that is essential to its function. Whether made of ceramic or metal, the honeycomb structure creates a larger surface area through which exhaust gases can be channeled, resulting in an optimal reaction. The exhaust gases from the engine are thus channeled through the catalytic converter, where they are converted and expelled from the exhaust into the atmosphere in a measurably cleaner state.

To achieve the best possible emission values for your vehicle, you’ll find various models in our online store. For example, the Racing Catalytic Converter / Sport Catalytic Converter, 200 CPI, Euro 4, compatible with various Audi and Passat models via plug and play. As you can already see, this catalytic converter also has the advantage of fitting perfectly in multiple car models; “plug and play” describes the simplicity of being able to replace the old catalytic converter with the new one on a 1:1 basis. Registration in accordance with §21 StVZO must be performed by an officially recognized expert and cannot be guaranteed. Since exhaust emissions depend on several factors such as exhaust temperature, engine power, displacement, etc., the specified Euro standard cannot be guaranteed either.

That leaves the question of the famous 100 or 200 cells, as seen on the sport catalytic converter pictured above. Right off the bat, let’s clear up the misconception that a 200-cell catalytic converter would actually have only 200 cells. This is because the designation always refers to “cells per inch,” which is equivalent to 2.54 cm. A 1.8T sports catalytic converter with 200 cells therefore has 200 cells per 2.54 cm – an area that will have a noticeably low-emission effect on your vehicle.

Whether you’re replacing an entire Exhaust System or if you’d like to replace the racing catalytic converter as a single part, you can get all the parts you need here—guaranteed to be of the highest quality—from the experts.
